90S8535 Datasheet 8-Bit Microcontroller with 4K/8K Bytes In-System Programmable Flash

Manufacturer: Atmel (now Microchip Technology)

General Description

The AT90S4434/8535 is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture.

By executing powerful instructions in a single clock cycle, the AT90S4434/8535 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
